Singapore Airline launches Blockchain based Digital Wallet; Convert air miles into crypto currency

Can frequent-fliers convert air miles into digital currency? Yes, at Singapore Airlines they can. From now on.
Thanks to the digital wallet app it has unveiled that will be accessible for users of the airline’s ‘KrisFlyer’ frequent flyer program. The aviation player is using its own in-house private blockchain technology, tested through a PoC, so that travelers can spend their air miles at retail establishments, hotels, petrol stations and other partner merchants (18 roped in so far). Other airlines may follow suit depending on how this model goes for SIA.
For now, the idea is taking off high.
